About The Position

Quantum Space is seeking a Principal Mechanical Engineer for Advanced Programs to drive mechanical architectures for next-generation spacecraft concepts—where requirements are evolving, the trade space is wide, and rigorous engineering judgment matters. This is a principal-level role: you will own ambiguous problems, set technical direction, and lead cross-functional execution toward buildable designs. Where You’ll Make an Impact Lead mechanical architecture and trade studies: packaging, mechanism concepts, structural layout, thermal hardware accommodation, serviceability, and integration strategy Own subsystem/interface definitions and drive closure with systems engineering: ICD inputs, keep-outs, access constraints, mass properties, alignment and stability needs Drive mechanical design maturation from concept to preliminary/detailed design: requirements, sizing logic, margins and assumptions, verification strategy Lead risk identification and mitigation planning (materials, joints, mechanisms, contamination, alignment, thermal distortion, integration sequence) Support prototype builds and rapid iteration: design-to-test loops, test learning incorporation, design updates Partner with procurement and suppliers: SOW technical inputs, technical evaluation, vendor coordination, design for manufacturability feedback loops Deliver review-quality content: architecture rationale, risk posture, verification approach, and build/test readiness

Requirements

• BS or MS in Mechanical Engineering or related field
• 10+ years mechanical engineering experience, with sustained ownership of complex hardware development
• Broad mechanical systems knowledge (structures, mechanisms, packaging, integration realities)
• Strong communication and leadership without relying on org-chart authority
• Comfort operating in ambiguity and driving crisp decisions with incomplete data
• Work location within the LA area
• To comply with U.S. Government space technology export regulations, including ITAR, applicants must be a U.S. citizen, lawful permanent resident, protected individual per 8 U.S.C. § 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.

Nice To Haves

• Experience Spacecraft mechanism design (release devices, deployment, latching, pointing structures)
• Experience supporting environmental testing and verification closure
• Creo/Windchill experience and ability to guide design quality standards

Responsibilities

• Lead mechanical architecture and trade studies: packaging, mechanism concepts, structural layout, thermal hardware accommodation, serviceability, and integration strategy
• Own subsystem/interface definitions and drive closure with systems engineering: ICD inputs, keep-outs, access constraints, mass properties, alignment and stability needs
• Drive mechanical design maturation from concept to preliminary/detailed design: requirements, sizing logic, margins and assumptions, verification strategy
• Lead risk identification and mitigation planning (materials, joints, mechanisms, contamination, alignment, thermal distortion, integration sequence)
• Support prototype builds and rapid iteration: design-to-test loops, test learning incorporation, design updates
• Partner with procurement and suppliers: SOW technical inputs, technical evaluation, vendor coordination, design for manufacturability feedback loops
• Deliver review-quality content: architecture rationale, risk posture, verification approach, and build/test readiness

Benefits

• Competitive salary, equity, and comprehensive benefits, including medical, dental, vision, generous leave, HSA, 401(k) matching, and equity participation.
